Showing validation issue details in REPL

[jasalt]

I had trouble in REPL not seeing any more detailed validation issue information than just ZodError without any message.

If I understood, the thrown ZodError exception would have to be caught and handled, or safe-parse output be checked instead, both manually, making interactive development not so convenient with the library.

I did not save a screenshot or anything as I was in a hurry switching from the library to a DIY solution, but can add extra details about reproducing if it can be of help.

Thank you.
Currently, the exception message is a fixed string “Zod Error”.
Certainly there is not enough information in the REPL.
Are you saying that you expected the exception message to be a description of the error?

@smeghead I'm not sure how much is correct to put into exception message. However, some way to provide detailed info in REPL would be useful.

Example of some Clojure Malli Schema error output https://github.com/metabase/metabase/wiki/Backend:-Metabase-Malli-Cheatsheet#validation.

I found that Malli Schema outputs a very nicely formatted message.

As a way to display phel-schema errors in the REPL in a somewhat understandable way, you might use a macro like the following.

(defmacro z-explain [& body]
  `(try
     ,@body
   (catch \Phel\PhelSchema\ZodError e
     (php/-> e (getIssues))))

If ZodError is encountered in z-explain body, return the error that caused it.

phel:1> (ns app
          (:require phel\schema :as z))
1
phel:2> (def my-schema (z/string))
1
phel:15> (z-explain (z/parse my-schema "tuna"))
tuna
phel:16> (z-explain (z/parse my-schema 12))
<PHP-Array [{:message Invalid type :paths []}]>
